10

the distance formula goes:
let (a,b) and (c,d) be 2 points with x coordinates a,c and y coordinates b,d respectively.

$d = \sqrt{{(c - a)}^{2} + {(d - b)}^{2}}$ $d=sqrt((c-a)^2+(d-b)^2)$

apply the formula to the problem

$d = \sqrt{{(- 6 - 4)}^{2} + {(7 - 7)}^{2}}$ $d=sqrt((-6-4)^2+(7-7)^2)$

$d = \sqrt{{(- 10)}^{2}}$ $d=sqrt((-10)^2$

$d = \sqrt{100}$ $d=sqrt(100)$

$d = 10$ $d=10$
